Renewed in the likeness of Christ,

Colossians 3:1-11
Since you have been raised with Christ, set your hearts on things above, set your minds on things above, not on earthly things.
Christ who is your life, appears, then you also will appear with him in glory.
Put to death what ever belongs to your earthly nature. And put on the new self, which is being renewed in knowledge in the image of its Creator. Christ is all and is in all.
There may be good sense in rules, renewed in the likeness of Christ, taking on his character.
Why?
For we are raised with Christ, He is my life so I should live out the image of God, to honor his holy name, so I have to live in holy life. Focus on things above and discard the nature of earth.
Renew in knowledge is the progress of my life to more closer to Christ. It takes time and needs effort to make it.
Christian should put everything on earth to death, for we are dead with Christ, and pursuit thing above, above is my hope and my strength. When look down on earth, there is no hope and full of sins.
How?
Get rid of old self but put on new self, renew myself day by day, more like His character.
